DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat cleaning device, and more particularly, to a vehicle seat cleaning device that removes dust by floating the surface of a vehicle seat by hitting the surface.

[0002]

2. Description of the Related Art Conventionally, a seat of a vehicle such as a train (hereinafter referred to as a seat) is removed from a vehicle at a vehicle factory,
After dust contained in the moquette (surface cloth) of the sheet itself and the cushioning material in the sheet is floated on the surface by "blowing high-pressure air" or "hitting by hand" manually, a brush and a brush are used. Had been cleaned by dusting it.

[0003]

However, in the "blowing of high-pressure air", it is necessary to blow very high-pressure air because dust in the sheet needs to be floated on the surface only by blowing air. . When air is blown at such a high pressure, dust is scattered in all directions, so that it is necessary to increase the dust collecting capacity of the dust collecting device and also to increase the suction port. For this reason, the device configuration becomes complicated and large, and the device itself becomes expensive.

[0004] In addition, "man tapping" is so-called 3K (dirty, hard, dangerous) heavy labor, and there is a problem of insufficient human labor.

[0005] In order to solve the above, wooden hitting devices, leaf spring hitting devices and the like are currently used. However, in wooden hitting devices, the tapping rod often breaks and the work must be stopped.In addition, the leaf spring type hitting device employs the method of hitting by the vibration of the leaf spring, so that satisfactory cleaning results can be obtained. Not been.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a vehicle seat cleaning apparatus capable of reducing the size and simplification of a dust collecting apparatus, eliminating labor shortages, and performing good cleaning without interrupting work for a long period of time. It is to provide.

SUMMARY OF THE INVENTION A vehicle seat cleaning apparatus of the present invention removes dust by floating the surface of a vehicle seat by hitting the surface of the vehicle seat. A shaft, and a plurality of hitters supported on the rotating shaft so as to extend in the outer circumferential direction of the rotating shaft. Each of the plurality of hitters is supported on the rotating shaft such that one end thereof is rotatable and the other end is extended in the outer peripheral direction of the rotating shaft, and the vehicle seat is capable of hitting the vehicle seat surface. A striking tool supported on the other end of the striking arm so as to be rotatable along the surface. Each of the plurality of hitters is arranged at intervals in the axial direction of the rotation axis, and extends in different directions about the rotation axis.

According to the vehicle seat cleaning device of the present invention,
Since the dust is floated on the seat surface by hitting the vehicle seat surface with the hitter, the dust collecting device can be made smaller and simpler than when dust is floated only by high-pressure spraying.

Further, since the rotating shaft supporting the hitting device is provided with a driving force by a motor or the like, there is no need to rely on manual labor, and the shortage of human labor can be eliminated.

Further, since the striking arm is rotatably supported by the rotating shaft, the striking arm rotates counterclockwise after the striking device hits the sheet surface. Thereby, the impact given to the hitting device at the time of hitting the sheet can be relieved, so that breakage of the hitting device can be prevented.

Further, since the hitting tool is rotatably supported by the hitting arm, the hitting tool in contact with the sheet surface after hitting the sheet rolls on the sheet surface. Thereby, the contact resistance between the sheet and the hitting tool is reduced.

Further, after the percussion device separates from the sheet, the percussion arm returns to the extended state due to the centrifugal force generated by the rotation of the rotating shaft, so that the surface of the sheet can be properly hit.

Further, since the sheet is hit by the rotational force, it is possible to perform better cleaning than using the vibration of the leaf spring.

Preferably, the above-described vehicle seat cleaning device further includes a rotating brush arranged so as to be able to contact the surface of the vehicle seat hit by the hitting device.

With this brush, dust floating on the sheet surface due to impact can be removed.

Next, the cleaning operation of the vehicle seat cleaning apparatus according to the present embodiment will be described.

Referring to FIGS. 1 and 2, first, a sheet 80 removed from the vehicle is placed on the entrance roller conveyor 51. Upon detecting the placement of the sheet 80, the control device 70 operates the sheet conveying device. The sheet 80 is carried into the cleaning booth 60 by the entrance roller conveyor 51.

The sheet hitting device 10 is operated by the detection signal of the sheet 80. That is, the driving force generated by the electric motor 3 is transmitted to the rotating shaft 1 via the sprocket chain, and the percussion device 2 rotates together with the rotating shaft 1. The brushing device 20 and the blowing device 30 are also operated, and each of the brushes 21a, 21b, and 22 rotates, and air is blown from the air blowing device 31.

The sheet 80 carried into the cleaning booth 60
Is conveyed by the in-machine roller conveyor 52 and is hit by the hitting tool 2b of the sheet hitting device 10. Due to the reaction at the time of the impact, the impact arm 2a rotates in a direction opposite to the rotation direction of the rotating shaft 1 with respect to the fixed bar 1a. Thereby, the impact at the time of the sheet hitting given to the hitting device 2 is softened. Thereafter, the hitting tool 2b of the hitting device 2 moves (rotates) while rotating along the upper surface of the sheet 80. Thereby, the contact resistance between the upper surface of the sheet 80 and the hitting tool 2b is reduced. The striker 2 separated from the upper surface of the sheet 80,
After returning to the state of being extended in the radial direction of the rotating shaft 1 by the centrifugal force due to the rotation of the rotating shaft 1, the surface of the sheet 80 is hit again.

In addition, the end face and the side face of the sheet 80 are swept by the rotating end face and the side face brush 22, so that dust floating on the end face and the side face is removed. Further, at the time of contact between the brushes 21a, 21b, 22 and the sheet 80, dust is wound up from the surface of the sheet 80 into the air stream by blowing air by the blowing device 30 and removed.

Thereafter, the air containing the dust in the cleaning booth 60 is sucked by the exhaust device 40, and after the dust is removed by the filter, is discharged to the outside.

The sheet 80 that has been cleaned in this way is
Is transported out of the cleaning booth 60 and is transported to a desired position by the exit roller conveyor 53.

In this embodiment, since the dust is floated on the surface of the sheet 80 by hitting the surface of the sheet 80 with the hitting device 2, the dust spreads in all directions as compared with the case where the dust is floated only by high-pressure spraying. Since the scattering can be suppressed, the dust collector can be reduced in size and simplified.

Further, since the rotating shaft 1 supporting the hitting device 2 is provided with a driving force by the electric motor 3, there is no need to rely on manual labor, and the shortage of labor can be solved.

Further, since the striking arm 2a is rotatably supported by the rotating shaft 1, after the striking device 2 strikes the surface of the sheet 80, the striking arm 2a recoils in a direction opposite to the rotation direction of the rotating shaft 1. Rotate. Thereby, the impact given to the hitting device 2 when the seat 80 is hit can be softened.
The breaker 2 can be prevented from being broken.

Further, since the hitting tool 2b is rotatably supported by the hitting arm 2a, the hitting tool 2b moving along the surface of the sheet 80 after hitting the sheet 80 rolls on the surface of the sheet 80. Thereby, the contact resistance between the sheet 80 and the hitting tool 2b is reduced.

Further, after the percussion device 2 separates from the sheet 80, the percussion arm 2a returns to a state of being extended in the radial direction of the rotation shaft 1 by centrifugal force due to the rotation of the rotation shaft 1, and the surface of the sheet 80 continues. Can hit properly.

Further, since the sheet 80 is hit by the rotational force, a better cleaning can be performed than when the sheet 80 is hit by utilizing the vibration of the leaf spring.

Further, since a plurality of hitters 2 extend in different outer peripheral directions with respect to one rotating shaft 1 around the rotating shaft 1, it is easy to balance the rotation of the rotating shaft 1. .

Although the sheet hitting device 10 has been described with respect to a state in which six rotating shafts 1 are arranged in parallel, the present invention is not limited to six, and any number of rotating shafts 1 may be arranged in parallel if there are a plurality of rotating shafts. It may be arranged.

The upper rotating brushes 21a and 21b are
One rotating shaft 1 may be provided one by one. The side and end face brushes 22 may also be arranged at positions sandwiched between the rotating shafts 1.
May be provided one by one.

The striking device 2 attached to the rotating shaft 1 has 6
The number is not limited to a book, and may be a plurality of books.

When it is necessary to hit the surface of the sheet 80 evenly, the second rotating shaft 1 is shifted from the hitting device 2 attached to the first rotating shaft 1 as shown in FIG. Preferably, a striker 2 is mounted. Specifically, the percussion device 2 attached to the first rotating shaft 1 and the percussion device 2 attached to the second rotating shaft 1 are alternately arranged in the axial direction, that is, attached to the first rotating shaft 1. It is preferable that the hitting device 2 attached to the second rotating shaft 1 be disposed between the hitting devices 2.

In the above-described embodiment, the configuration is described in which the upper surface of the sheet 80 is directed upward, and the striking device 2, the brushes 21a, 21b, and the air blowing device 31 are disposed above the sheet 80. May be adopted, and the striking device 2, the brushes 21a, 21b, and the air blowing device 31 are arranged below the seat 80. In this case, the upper surface of the sheet 80 may be in contact with the transport roller. In this case, the dust coming out of the sheet 80 falls downward. Therefore, if the dust is also sucked from below, the cleaning effect and the dust absorbing effect are further improved.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

[0057]

As described above, according to the vehicle seat cleaning apparatus of the present invention, the dust is floated on the seat surface by hitting the vehicle seat surface with the hitting device, so that the dust is floated only by high-pressure spraying. The dust collector can be made smaller and simpler than in the case.

Further, since the rotating shaft supporting the hitting device is provided with a driving force by a motor or the like, there is no need to rely on manual labor, and the shortage of labor can be solved.

Further, since the striking arm is rotatably supported by the rotating shaft, the striking arm rotates counterclockwise after the striking device hits the sheet surface. Thereby, the impact given to the hitting device at the time of hitting the sheet can be relieved, so that breakage of the hitting device can be prevented.

Further, since the hitting tool is rotatably supported by the hitting arm, the hitting tool in contact with the sheet surface after hitting the sheet rolls on the sheet surface. Thereby, the contact resistance between the sheet and the hitting tool is reduced.

After the percussion device separates from the sheet, the percussion arm returns to the extended state due to the centrifugal force caused by the rotation of the rotating shaft, and the perforated sheet surface can be continuously hit.
